v` Application filed February 6, 1918. Serial No. 215,664.

To all 't0/1.0m t may concern: Beit known that I, BERT CARLISLE, acitizen of the United States, residing at Santa Ana, in the county ofOrange and State of California, l1. ve invented new and usefulImprovements in Spacing Devices for Wrapping-Paper Rolls, of which thefollowing is a specification.

My object is to make a roll paper cutter having a spacing deviceparallel with the cutting edge of the paper cutter and adapted to engageunder the paper and guide 1t outwardly from the roll so that it may beeasily grasped and torn o, and my invention consists in the novelfeatures herein shown, described and claimed.

Figure 1 is a perspective of a paper cutter provided with a spacingdevice in accordance with the principles of my invention.

Fig. 2 is a perspective of the cutter bar and spacing device removedfrom the supporting arms.

Fig. 3 is an enlarged cross-sectional detail on the line 3--3 of Fig. 1and illustrating the operation.

The roll paper cutter 1 comprises standards 2 and 3, a top 4 connectingthe upper ends of the standards, horizontally alined bearings 5 in thestandards to support the spindle 6 upon which the roll paper 7 ismounted, and spring-pressed arms 8 connected to the top 4 and projectingforwardly.

The parts 2-8 are or may be of the ordinary construction.

In the construction shown in Figs. 1, 2 and 3, I apply the cutter bar 9to the outer ends of the spring-pressed arms 8 and attach the spacingbar 10 to the cutter bar.

The details of the cutter bar 9 are as follows: The cutter bar ispreferably formed of sheet metal. A piece of metal is cut substantiallyrectangular and the sheet of metal is bent longitudinally on the line 11to form the flat straight blade 12 having the straight cutting edge 13at its forward side and the attaching bar 14 extending upwardly andbackwardly from the line l1 and having sockets 15 and 16 to receive thespringpressed arms 8. The socket 15 is formed by cutting longitudinalparallel slits 17, 18 and 19 in the metal and bending the portion 20between the slits 17 and 18 backwardly and the portions 21 and 22forwardly, the portion 21 being between the slits 18 and 19 and theportion 22 being above the slit 17.

arm 8 has a recess 23 formed from its back side to lit the portion 20and the arm is inserted downwardly back of the portions 21 and 22 and infront of the portion 20, and the portion 2O hammered into the recess 23.The other arm 8 is connected to the socket 16 in a similar manner, so asto rigidly connect the cutting edge to the spring-pressed supportingarms and so as to hold the cuttingedge 13 outwardly from the roll paperThe spacing bar 10 is cut and pressed from sheet metal and comprises theguide plate 24 fitting below the plate 12 and having a notch 25 in itsfront face, the spacing bar 26 bent upwardly from the back side of theplate 24, and the flanges 27 bent upwardly and forwardly from -the endsof the plate 24 and the ends of the speacing bar 26 to lt against thelower faces of the ends of the plate 12 and the back faces of the endsof the attaching bar 14, the parts being rigidly secured together alongthe lines 28 by brazing, welding, soldering or the like. The upper rearedge 29 of the spacing bar 26 is adapted to bear directly upon the faceof the roll 7 so that the edge 80 of the paper will pass over the edge29 and downwardly in front of the bar 26 behind the bar 14 and thenforwardly upon the plate 24 under the plate 12.

When the paper is torn off along the edge 13, the untorn piece will layupon the plate 24 with the edge 30 at the edge 13 and when another pieceof paper is desired the operator may pass his lingers under the paperthrough the notch 25 and pull the paper forwardly to the desired extent.In this way the edge of the untorn paper is always spaced away from theroll in position convenient to the operator instead of clinging to theroll, as in the old cutters. The back bar 26 rides upon the face of theroll, the spacing flanges 27 hold the attaching bar 14 outwardly fromthe roll and the plate 24 guides the free edge of the paper outwardlyfrom the roll.

Various changes may be made in the details of construction withoutdeparting from the spirit of my invention as claimed.

I claim:

A spacing device for roll paper cutters, comprising the combination witha paper cutter construction having spring-pressed arms, of a piece offiat metal bent longitudinally to form a flat straight blade and anattaching bar, lneans fr connecting the atblade and bar to bear againsta paper roll and guide the paper between-the'bladeand' spacing bar; saidspacing bar construction-- comprising a -pecef of sheet metal i out"and*l bent to form a guide plate,I a spacing bar/,'4-

and flanges extending upwardly and fr- Wardlyfm the ends of 4"the guideplate and 10 the ends of the spacing bar and ttng againsttthealdwerfaceswofn the iends of the blade and the back faces of theends of the attaelingvbary-tlleparts being rigidly secured together. 15In'testnony whereof I have .signedsmylfx name .to- Athis speccaton.
